Tank Type Heaters
Storage water heaters are the most common type of water heater used in both residential and commercial applications. Storage water heaters incorporate heating elements or a gas burner and tank into a single unit. Electric units are typically available in one- to 120-gallon capacity with input ratings of 1 kW to 54 kW. Most smaller units, including almost all units applied in residences, are dual-element units with an upper heating element and a lower element controlled to prevent simultaneous operation. A typical electric resistance storage water heater is shown here:
Larger commercial water heaters may have several banks of elements that are allowed to operate simultaneously. Virtually all commercial electric units are 208 V or higher, either single or three phase. With 120-V service, maximum input capacity is limited to 1.9 kW or less.
The most common commercial gas storage water heaters vary in size from 20 to 100 gallons. Input ratings range from 30 to 600 kBTUH.
In almost all code jurisdictions, storage water heaters or hot water tanks must be ASME labeled if their capacity is greater than 120 gallons or if the rated input is 200 kBTUH or more. Higher-cost ASME-rated water heaters are available in capacities up to 5000 gallons and input ratings of 2000 kW and 750 kBTUH. As an alternative to high-cost ASME-rated tanks, several smaller, non-ASME-rated units may be used to provide equivalent capacity.
Most electric storage water heaters are controlled by surface-mounted adjustable thermostats, although larger units may use immersion thermostats. In electric units, the upper and lower elements are controlled by separate thermostats which are adjustable from about 110 to 180°F. Fuel-fired water heaters have a single immersion thermostat. On all water heaters, control resolution is coarse and accuracy is limited.

Electric Water Heater Replacement
Cold water enters the bottom of the tank through a dip tube inside the tank much like a gas water heater. Hot water is drawn off of the top of the tank through the hot water line. The element in the water heater is basically an electric rod that heats up red hot to heat the water; most electric hot water heaters have two elements and alternate when heating.
Water Heater Maintenance Makes a Difference
